Title: Improvements in Machine Guns.
Inventor: IMRAY OLIVER
IPC: F41A9/33
Filed: 1917-05-21
Abstract: 133,352. Imray, O., (Colt's Patent Fire Arms Manufacturing Co.). May 21, 1917. Machine guns.- Relates to recoiloperated guns of the kind described i n Specifications 1 4 9 2 1 / 0 0 and 133,329, and consists mainly in pivoting the cartridge-feed extractor to the breech-bolt and the ejector to the extractor so that both are removable with the bolt. As shown in Fig. III., the rear part of the bottom nf the casing is closed by a plate L, an open space being left in the front part for the discharge of the spent cartridge cases. Similarly, the top of the casing is covered by a plate H, which leaves the front part open for the insertion of the cartridge belt; this front part is then closed by a hinged cover G, which is locked in place by a sliding bolt I on the plate H. The rear end of the casing is closed by a vertically-sliding plate J inserted from the top, and locked in place by the bolt I. This bolt is normally held in place by a spring catch i, but it can be pushed back to release the hinged cover G and then pushed forward to release the backplate J after the hinged cover U has been swung up. The cartridge belt passes over the rear end of the bairel, and the belt-feeding slide g and rocking lever Y are carried by the hinged cover. The lever Y is of spring steel, and there is a clearance between it and the cover, so that when the cover is swung down, if the stud z of the lever does not fit into the groove Z at the top of the breech-bolt E, this end of the lever will spring up without preventing the cover from being fully swung down and locked; then, when the breechbolt is worked by its handle, the stud of the lever snaps into its groove as soon as the groove comes underneath the stud. The cartridges are extracted from the belt by the nose 1 of a pawl X pivoted at 9 to the breech-block. As the recoil proceeds, the pawl is lowered by a cam 3 on one side of the breech casing. On the return stroke, the pawl is still further lowered by a cam 4, Fig. VI., acting on a stud 7 on the pawl. The cartridge is now in line with the barrel and is forced into it. At the end of the stroke, the pawl is raised by a cam 5 acting on the same stud 7; and a spring blade 2 carried by the hinged cover G presses the nose of the pawl into the groove of the next cartridge, the belt having been moved one step forward by the mechanism previously mentioned. The rims of the cartridges are guided by a vertical groove e<3>, e<4>, Fig. XIV., in the face of the breech-bolt E, one edge e<4> of the groove being cut away at the top to permit the entry of the rims of the cartridges. The spent cartridge case is ejected by a tooth x pivoted to the nose of the feed-extractor pawl X and urged down by a spring, which also urges the stud 7 laterally outwards ; at the beginning of the recoil, this stud is pressed in by a bevel 6 on the cam 4; and, when the pawl X is moved to its lowermost position during the forward stroke of the breech-block, the tip of the tooth x is caught by a bevelled edge along the barrel extension.

Abstract: 636,336. Load-handling machines. FAURE, S. March 13, 1947, Nos. 7043 and 7044. Convention dates, Sept. 5, 1945 and May 31, 1946. [Classes 78 (ii) and 78 (iii)] In hauling and hoisting gear operated by means of a metal cable, of the type including two movable blocks 6, 7 adapted to move simultaneously in opposite directions over the cable 4 for gripping it in their jaws and releasing it in turns under the action of a lever control providing for the progressive rising of the load and pivotally connected with each block so as to provide in alternation for the opening of either jaw when the block is moved in a predetermined direction, a progressive downward movement of the load is produced by a second lever controlling in opposite directions the blocks 6 and 7 through at least one further link 23 or 24 actuating directly the jaw-controlling levers pivotally carried by the blocks in order to open either jaw while the corresponding block moves in a direction opposite to the first predetermined direction. The downward movement is controlled by a lever inserted in a socket 19 which is coupled by gudgeons 21, 22 to connecting rods 23, 24 actuating the jaws in the blocks 6, 7 respectively through levers 34, 35. Two springs 25 are housed in tubes 26 secured to parts 27 connected together by a pin 28 which is free to move in slots 29. The springs transmit their opposing force in the direction of the arrow 31 to pivots 32, 33 which connect the connecting rods 23, 24 respectively with the levers 34, 35 controlling the jaws in the blocks 6 and 7 so that when inoperative the springs urge the jaws into their cable braking position. To lower the load the socket 19 is actuated in alternating directions around its pivot 28 so as to move the connecting rods 23, 24. On actuating the socket 19 in the direction of the arrow 38 the jaws in the block 6 are disengaged and release the cable 4 along which the block 6 sinks whilst the jaws in the block 7 grip the cable. On actuating the socket 19 in the opposite direction the jaws in the block 7 open and the block 7 sinks whilst the block 6 remains clamped to the cable. To keep both jaws open simultaneously for

Title: Cushion attachment for stadium and similar seats
IPC: A47C1/16
Filed: 1954-03-11
Abstract: 739,849. Coin-freed apparatus. McLANEY MANUFACTURING CORPORATION. March 11, 1954 [March 23, 1953], No. 7093/54. Class 27. [Also in Group XIV] Seat covers.-A cover or cushion pad 5 for a stadium or similar seat 4 is normally stowed underneath the seat, with its rear end resting on a hook 11 and a lug 25 on a tab 24 at its forward end secured in a coin-freed mechanism 12. On insertion of a coin, the tab is released and the pad can be moved to the top of the seat, an eye 7 on a tongue 6 by which the pad is permanently connected to the seat sliding along a rod 8 to allow this movement. To allow of fitting the rod 8 to different sizes of seat, its front end may be screwed to engage a nut 17 within the coin mechanism or may have grooves of which a selected one is clasped between parts of the coin mechanism casing. The pad may also have a cover for the seat back rest attached to it and a loop on the back rest cover may engage the hook 11 to hold the pad in the stowed position. The legend OCCUPIED may be inscribed on the top surface of the pad. Coin-freed mechanism.-With the pad in inoperative position, the lug 25 is inserted through a slot 26 in the front plate 21 and through a registering slot 45 in a locking slide 30. A spring- loaded actuating slide 31 is then moved to the left by means of a handle 38 to engage the locking slide and engage a longitudinal slot 44 over the shank of the lug, thus preventing its withdrawal. The locking slide is held in this position by the engagement of a detent 53 on a resilient plate 33 with another slot 46 but the insertion of a coin through a slot 39 into the space between arcs 40 and 43 on the two slides allows the locking slide to be moved further to the left until the lug 25 lies in a large space adjacent the arcs 40 and 43 and is free to be pulled out. In the movement of the parts to the lug-releasing position, the detent 53 on the resilient plate 33 slips out of the slot 46 and then snaps into the slot 45, to hold the slide 31 in a position that prevents removal of the coin. To remove the coin, a serviceman turns a key in a lock 58 and causes a cam finger 35 to engage a surface 56 on the plate 33 so that the detent 53 is removed from the slot 45 and the two slides are returned to the right, in which position the coin can be picked from the slot 39.

Title: Improvements in or relating to a process of converting hydrocarbons
Inventor: DEGNEN WILLIAM JOSEPH
IPC: C10G11/18
Filed: 1951-03-30
Abstract: In a process for the conversion of hydrocarbons (e.g. gas oil to gasoline), by contact with a fluidized conversion catalyst and regeneration of the fluidized catalyst with an oxygen-containing gas, catalyst from the reaction zone 11 is withdrawn by gravity through stripping zone 12 and pipe 21 to the regeneration zone 19, into which regeneration gas is introduced at 18, and regenerated catalyst is removed from the bottom of zone 19 as an annular stream and returned to the lower part of the reaction zone via pipe 20 together with a stream of hydrocarbon fluid, which may be mixed with steam.  The system avoids <PICT:0695319/III/1> the use of standpipes, eliminates sharp bends, and will function with varying levels in the regeneration bed.  A well 14 may be provided at the bottom of zone 19 for shielding pipe 20 from the regeneration gas, and steam may be admitted at 30 as a stripping medium.  Entry of catalyst into pipe 20 is controlled by valve 22 through the hollow stem of which hydrocarbon is introduced.  The valve may be operated manually or by hydraulic or pneumatic means, and may be provided with a device to release pressure due to expansion of the pipe 20.  Plug valve 36 regulates passage of the catalyst to the regeneration zone.  Steam is introduced into stripping zone 12 through pipe 35, and cyclone separators 32, 39 remove entrained catalyst.
